Zach Pop signed a one-year contract with the New York Mets and joined their bullpen Saturday before a Subway Series game against the Yankees.

The Mets look to extend their win streak to four in the second game of the Subway Series at 4:10 p.m. Saturday against the Yankees at Citi Field.

Subway Series continues this weekend when the New York Mets host the crosstown rival New York Yankees for three games at Citi Field. It is potentially a World Series preview, though neither team has looked the part of a World Series contender the last 3-4 weeks.
